Session Abstract

In 2006, Université Laval, located in Quebec, Canada, started to decarbonize their heating network by using their chilled water network as an energy loop. Decentralized heat pumps harvest heat from this energy loop and produce low temperature heating water (110°F) for many buildings on campus. This system has been operating for more than 15 years. It allowed to reduce the campus energy intensity from 1.71GJ/m2 to 1.40 GJ/m2 and GHG emissions by 10,000 tonnes yearly.  The presentation will cover design aspects, lessons learned, total yearly energy savings, yearly GHG reductions, operational changes that occurred on campus as well as building design requirements for future buildings connecting on the energy loop.
